SKIP HOIST.

Application filed December 29, 1922-.

at the base of the structure from a car, or

other carrier.

One ob]ect of my invention is to reduce the ground space occupied by the structure,

' which enables the structure to be used where the space is limited.

A further object of the invention is to provide a single structure in which the storage hopper is above the tracks and the discharge hopper is below the tracks, the skip hoist tracks extending in the same direction under and over the structure, as fully described hereinafter, reference being had to the accompanying drawings, in which:

Fig. 1 is a side view of my improved skip hoist structure;

Fig. 2 is a view in tront elevation with the base of the structure in section; and

Fig. 3 is a view illustrating a modification of the invention.

Referring to the drawings, 1 is the frame of the skip hoist structure. Carried by the upper portion of the frame is the storage hopper 2 having an opening 8 through which the material is discharged into the hopper and two spouts 4t and One spout, in the present instance, extends into a build ing 6 to the chute 7 of a feeding apparatus 8 for feeding the boiler furnaces 9, shown in diagram in Fig. 1. The chute 5 leads to a chute 10 directly above the railway tracks 11, extending through the structure 1 and on which the cars 12 travel so that. when it is desired to load a car with material from the hopper, the valve 13 can be turned to direct material into the chute 5.

14; designates the structure within the frame 1, supporting the tracks 11. Directly below this structure is the receiving hopper 15, which has a chute 1.6 provided with a Serial No. 609,618.

pivoted section 17 that is actuated by the bucket 18.

l Vhen the bucket is in the position shown by full lines, Fig. 1, directly under the frame 1. the pivoted chute 17 is in position to allow material to flow directly into the bucket. hen the bucket is raised, the chute 17 is turned on its pivot by the bucket closing the hopper 16 until the bucket returns and trips the mechanism to turn the chute 17 in position over the bucket 18, after which the material flows into the bucket and the above operation is repeated.

20 designates the track for the skip hoist bucket 18, which has wheels 19 adapted to the rails of the track. The track has a vertical portion 20, a lower inclined portion 20", and an upper inclined portion 20 extending in the same direction laterally as the inclined portion 20 and forming a letter C. 21 is a guide rail, which extends into a pit 22 under the frame 1, but is discontinued at the upper end, as shown in Fig. 1.

23 designates a pulley at the upper end of. the frame 1. A hoisting rope 24 passes around this pulley. One end of this rope is guided by sheaves to suitable power mechanism in a house 25, while the other end of the rope is connected to the bail 26 of the bucket 18. This bail is so arranged that, when the bucket is in the position illustrated by dotted lines in F 1, it discharges its load into the opening 3 of the hopper 2. The cover 27 of the hopper is pivoted at 28 and is raised by the bail when the bucket is elevated.

The operation is as follows: l Vhen the hopper 2 is to be loaded with material from a car, the car is run onto the railway tracks 11 under the hopper and the material is discharged from the car into the receiving hopper 15. Motion is imparted to the bucket so that it will be raised and lowered continuously, carrying material from the bottom of the structure to the top and discharg ing its contents into the opening in the top of the hopper 2. When it is desired to convey the material to a boiler room, as shown, the valve 13 is moved in order to direct the material through the chute 1.

When, at any time, it is desired to load a car from the hopper 2, the car is run onto the tracks 11 and the material is directed through the chutes 5 and 10 and into the car, which is directly under the chute 10.

In Figs. 1 and 2, the track is shown directly under the main hopper, while the receiving hopper is directly under the track. The rails of the skip hoist are located at the side of the main frame and the lower section or these rails extends under the structure, while the upper section extends over the structure, consequently, the structure can be located in a comparatively limited space.

In Fig. 3 a modification is illustrated, in which the upper hopper 2 is located at one side of the skip 'hoist structure 1. In this construction, the upper, inclined portion 20 of the skip hoist track is carried over the hopper. This hopper may be supported on a building adjacent to the skip hoist struc ture, or it may be supported on a separate structure, if desired, either independent of, or connected to the skip hoist structure. In any construction, the skip hoist tracks form the letter C. The lower, inclined section extends under the railway tracks and the upper section extends in the same direction laterally as the lower section and over the railway tracks and over a hopper at a point above the tracks.

I claim:

1. The combinationin a skip hoist structure, of a railway track; a hopper arranged to receive material from a car on the track; a track for a skip hoist bucket having upper and lower inclined sections extending under the hopper and railway track, the upper inclined section extending in the same direction, laterally, as the lower section; and a skip hoist bucket arranged to travel on the said skip hoist track.

2. The combination in a skip hoist structure, of a railway track and a storage hopper; a hopper under the track; and a track for a skip hoist bucket having a lower inclined section extending under the railway track and the lower hopper, the upper sec tion of the skip hoist track extending in the same direction, laterally, as the lower section over the track and over a storage hop per.

The combination in a skip hoist, of a main frame; a hopper supported by the upper portion of the frame; a railway track under the hopper; a skip hoist bucket; and a track therefor located at the side of the structure, the lower portions of said skip hoist track extending under the structure and the upper portions of the track extending over the structure.

4. The combination in a skip hoist, of a supporting frame; a main hopper on the upper portion of the frame; a railway track located under the hopper and between the side members of the frame; a receiving hopper under the track; a skip hoist bucket; and a track for said bucket, said skip hoist track extending vertically at one side of the structure, the lower portion of the track being inclined and extending under the structure so that the bucket receives material from the receiving hopper, the upper portion of the track extending over the main hopper so that the bucket, when it reaches a point above the hopper discharges its contents into the hopper.
